According to the relevant requirements of the Coal Mine Safety Regulations, the goaf should be sealed in a timely manner according to regulations, and the gas composition and air temperature inside and outside the sealing wall should be measured and analyzed. The coal mine multi parameter monitoring system for sealed area is specifically designed for monitoring multiple parameters such as methane, carbon monoxide, carbon dioxide, oxygen, ethylene, acetylene, pressure, temperature, etc. inside and outside the coal mine sealing wall. It also has high-precision pressure sensors to monitor the pressure values inside and outside the wall in real time. Through the linkage with valves, the pressure of the wall can be dynamically adjusted, achieving automatic, real-time, and 24-hour uninterrupted online monitoring, providing accurate, stable, and reliable monitoring data for fire monitoring in sealed area, effectively reducing or avoiding fire accidents and losses, achieving monitoring, early warning, and pre evaluation of fire prevention effects, which has important guiding significance for the coal production safety.
